XXL之整合SpringBoot

ゝ一世哀愁。 2022-04-03 09:18 137阅读 0赞

### 一、xxl-job-admin ###

①执行数据库脚本tables\_xxl\_job.sql，生成库表

②通过nginx为调度中心集群做负载均衡，分别启动8001和8002端口的xxl-job-admin实例，建议修改xxl-job-admin的打包方式，将配置文件application.properties从jar包中剥离出来，方便修改配置

application.properties

### web
    server.port=8001
    server.context-path=/xxl-job-admin
    
    ### resources
    spring.mvc.static-path-pattern=/static/**
    spring.resources.static-locations=classpath:/static/
    
    ### freemarker
    spring.freemarker.templateLoaderPath=classpath:/templates/
    spring.freemarker.suffix=.ftl
    spring.freemarker.charset=UTF-8
    spring.freemarker.request-context-attribute=request
    spring.freemarker.settings.number_format=0.##########
    
    ### mybatis
    mybatis.mapper-locations=classpath:/mybatis-mapper/*Mapper.xml
    
    ### xxl-job, datasource
    spring.datasource.url=jdbc:mysql://192.168.124.129:3306/xxl-job?Unicode=true&characterEncoding=UTF-8
    spring.datasource.username=root
    spring.datasource.password=123456
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    
    spring.datasource.type=org.apache.tomcat.jdbc.pool.DataSource
    spring.datasource.tomcat.max-wait=10000
    spring.datasource.tomcat.max-active=30
    spring.datasource.tomcat.test-on-borrow=true
    
    ### xxl-job email
    spring.mail.host=smtp.qq.com
    spring.mail.port=25
    spring.mail.username=xxxxxx@qq.com
    ###填的是SMTP授权码,不是邮箱密码
    spring.mail.password=xxxxxx
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true
    
    
    ### xxl-job login
    xxl.job.login.username=admin
    xxl.job.login.password=123456
    
    ### xxl-job, access token
    xxl.job.accessToken=myAccessToken
    
    ### xxl-job, i18n (default empty as chinese, "en" as english)
    xxl.job.i18n=

③配置并启动Nginx

http {
           upstream xxl{
    	 server 192.168.124.129:8001;
             server 192.168.124.129:8002;
        }
        server{
            listen       8088;
     
            location / {
                proxy_pass  http://xxl;
            }
        }
    }

③成功后，我们可以通过nginx来访问xxl-job-admin集群了

http://192.168.124.129:8088/xxl-job-admin

配置执行器和任务

### ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0MzEzNjM1_size_16_color_FFFFFF_t_70 2][] ###

路由策略置为轮询，cron表达式设置为每五秒调度一次

### 二 、执行器项目 ###

新建执行器项目XXL-Task，pom.xml文件引入依赖，似乎存在与SpringBoot版本不兼容的情况，启动会报异常，此处采用的SpringBoot版本为1.5.18.RELEASE

<parent>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-parent</artifactId>
    	<version>1.5.18.RELEASE</version>
    	<relativePath />
    </parent>
    
    <dependency>
    	<groupId>com.xuxueli</groupId>
    	<artifactId>xxl-job-core</artifactId>
    	<version>2.0.1</version>
    </dependency>

application.properties文件（Appname类比MQ的Group）

server.port=9001
    
    #xxl-job调度中心工程的地址
    xxl.job.admin.addresses=http://192.168.124.129:8088/xxl-job-admin 
    #xxl-job executor
    xxl.job.executor.appname=testAppName
    xxl.job.executor.ip=
    xxl.job.executor.port=9999
    #xxl-job log path 
    xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
    #xxl-job, access token 
    xxl.job.accessToken=myAccessToken
    #执行器Log文件定期清理功能，指定日志保存天数，日志文件过期自动删除。限制至少保持3天，否则功能不生效
    xxl.job.executor.logretentiondays=-1

XxlJobConfig

package com.yj.config;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;
    import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
    
    @Configuration
    @ComponentScan(basePackages = "com.yj.handler")
    public class XxlJobConfig {
    
    	@Value("${xxl.job.admin.addresses}")
    	private String adminAddresses;
    
    	@Value("${xxl.job.executor.appname}")
    	private String appName;
    
    	@Value("${xxl.job.executor.ip}")
    	private String ip;
    
    	@Value("${xxl.job.executor.port}")
    	private int port;
    
    	@Value("${xxl.job.accessToken}")
    	private String accessToken;
    
    	@Value("${xxl.job.executor.logpath}")
    	private String logPath;
    
    	@Value("${xxl.job.executor.logretentiondays}")
    	private int logRetentionDays;
    
    	@Bean(initMethod = "start", destroyMethod = "destroy")
    	public XxlJobSpringExecutor xxlJobExecutor() {
    		XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
    		xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
    		xxlJobSpringExecutor.setAppName(appName);
    		xxlJobSpringExecutor.setIp(ip);
    		xxlJobSpringExecutor.setPort(port);
    		xxlJobSpringExecutor.setAccessToken(accessToken);
    		xxlJobSpringExecutor.setLogPath(logPath);
    		xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);
    		return xxlJobSpringExecutor;
    	}
    }

MyJobHandler

package com.yj.handler;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Component;
    import com.xxl.job.core.biz.model.ReturnT;
    import com.xxl.job.core.handler.IJobHandler;
    import com.xxl.job.core.handler.annotation.JobHandler;
    import com.xxl.job.core.log.XxlJobLogger;
    
    @JobHandler(value = "myJobHandler")
    @Component
    public class MyJobHandler extends IJobHandler {
    	
    	private static final Logger log = LoggerFactory.getLogger(MyJobHandler.class);
    
    	@Value("${server.port}")
    	private String port;
    	
    	@Override
    	public ReturnT<String> execute(String param) throws Exception {
    		XxlJobLogger.log("Hello World,port:"+port);
    		log.info("Hello World,port:"+port);
    		return SUCCESS;
    	}
    }

分别启动server.port=9001,9002端口的执行器实例，其中,xxl.job.executor.port=9999,9998，xxl.job.executor.appname都为testAppName

启动后在xxl-job-admin控制台（有点类似Eureka）已经能看到注册成功的执行器实例了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0MzEzNjM1_size_16_color_FFFFFF_t_70 3][]

查看执行器控制台日志，发现xxl-job-admin对9001和9002的XXL-Task项目进行了负载均衡的调度（类比MQ集群模式）

15:00:53.254 logback [Thread-28] INFO  com.yj.handler.MyJobHandler - Hello World,port:9002
    15:00:58.284 logback [Thread-16] INFO  com.yj.handler.MyJobHandler - Hello World,port:9001
    15:01:03.261 logback [Thread-28] INFO  com.yj.handler.MyJobHandler - Hello World,port:9002

我们再将路由策略置为分片广播的模式（类比MQ广播模式）

15:14:43.277 logback [Thread-28] INFO  com.yj.handler.MyJobHandler - Hello World,port:9002
    15:14:48.281 logback [Thread-28] INFO  com.yj.handler.MyJobHandler - Hello World,port:9002
    15:14:53.264 logback [Thread-28] INFO  com.yj.handler.MyJobHandler - Hello World,port:9002
    
    15:14:43.343 logback [Thread-26] INFO  com.yj.handler.MyJobHandler - Hello World,port:9001
    15:14:48.299 logback [Thread-26] INFO  com.yj.handler.MyJobHandler - Hello World,port:9001
    15:14:53.340 logback [Thread-26] INFO  com.yj.handler.MyJobHandler - Hello World,port:9001

我们再验证下邮件的报警功能，在执行器任务中抛出一个异常int i=1/0，会收到告警邮件
